Important for the resorption of phosphate by the kidney (PubMed:7826357). May be involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane (PubMed:7826357). Plays a role in urate transport in the kidney (PubMed:25252215, PubMed:27906618). {ECO:0000269|PubMed:25252215, ECO:0000269|PubMed:27906618, ECO:0000269|PubMed:7826357}. This is the function of ENSG00000124568 (SLC17A1, solute carrier family 17 member 1).
